Title: can't eject cd on mac mini
Post by: John3101 on May 25, 2011, 05:43:51 PM

I apologize for the general dumbness of this question, but I can't eject the cd from my mac mini (I'm a newbie to both the mac & tiny core).  What i do is to open the Terminal and then type

umount /mnt/hdc

when then gives me the reponse "can't umount '/mnt/hdc':  no such file or directory"

If I try

eject /dev/hdc

I get "can't open '/dev/hdc':  no such device or address"

Clearly I'm doing something wrong, but I don't know what.   Thanks in advance for any help.

Try just 'eject'
cat /etc/fstab to see what devices were found.

eject along gives "can't open /dev/cdrom": no  such file or directory"
cat /etc/fstab gives
proc
sysf
devpts
tempfs

as devices found.

I should also mention that the cd in question was burned today from the tiny core iso download with no modifications.

It appears that your CD drive or controller is not supported by TC.

Or a hard drive or a USB drive or anything else according to fstab. How did he boot?

The boot loader uses BIOS calls to load an object into memory, and then jumps to an enrty point.
The loaded object may or may not have any disk/CD drivers.
One often loaded object is memtest86 which has no DVD drivers.

Hi John3101
Open a terminal and type  dmesg > dmesg.txt  and attach the file to your next post.

@gerald_clark: So if it does not find a suitable driver it won't show up in fstab I guess.

What version of TC is being booted?
The latest release is 3.6.

Apart from the suggestion in reply #6 to share with us the whole 'dmesg' output another command I've found to help in your situation might be to run
    blkid /dev/[hs][dr]*
(which should list information about all IDE and SATA devices).

Thank you everyone for your helpful suggestions.

In the end, I decided that I needed to use my Mac more than I needed to figure out the issue with Tiny Core.  So I rebooted the Mac with the Option key held down, which brings up a list of boot devices, and I was able to boot from the Mac HD, and then eject the CD, which then allowed the Mac to boot normally.
